Abstract

A cable connector assembly includes: a mating portion; a flat cable electrically connecting with the mating portion, the flat cable having plural wires and an outer boot enclosed the wires, the wires including a first wire and a second wire; an inner mold enclosing a part of the mating portion and a part of the flat cable; and a shielding shell enclosed the inner mold, wherein the first wire is a core wire directly enclosed by the outer boot and the second wire comprises a core wire and an insulative layer enclosing the associated core wire.

What is claimed is: 
     
       1. A cable connector assembly comprising:
 a mating portion; 
 a flat cable electrically connecting with the mating portion, the flat cable comprising a plurality of wires and an outer boot enclosing the wires, the wires comprising a first wire and a second wire; 
 an inner mold enclosing a part of the mating portion and a part of the flat cable; and 
 a shielding shell enclosing the inner mold; wherein 
 the first wire is a core wire directly enclosed by the outer boot; and 
 the second wire comprises a core wire and an insulative layer enclosing the associated core wire. 
 
     
     
       2. The cable connector assembly as claimed in  claim 1 , wherein the second wire comprises a pair of power wires, and the power wire has a shield layer enclosing the insulative layer. 
     
     
       3. The cable connector assembly as claimed in  claim 1 , wherein the shielding shell has a same cross section in the whole front-to-back direction, and the shielding shell encloses the periphery of mating portion and inner mold in a front-to-back direction. 
     
     
       4. The cable connector assembly as claimed in  claim 1 , further comprising a back cover mounted at a rear of the inner mold, and wherein the shielding shell encloses the periphery of back cover in a front-to-back direction. 
     
     
       5. The cable connector assembly as claimed in  claim 2 , wherein the shield layer comprises a plurality of spiral wires extending along the power wires. 
     
     
       6. The cable connector assembly as claimed in  claim 5 , further comprising a collar, and wherein the shield layer has an exposed part turned out of the outer boot, and the collar crimps the exposed part and electrically connects with the shield layer and the shielding shell. 
     
     
       7. The cable connector assembly as claimed in  claim 6 , wherein the collar has a tuber, the tuber exposing out the inner mold to electrically connect with the shielding shell. 
     
     
       8. The cable connector assembly as claimed in  claim 6 , wherein the collar has an integral spring tab exposing out of the inner mold for electrically connecting with the shielding shell. 
     
     
       9. The cable connector assembly as claimed in  claim 6  further comprising a conductive pad, and wherein the inner mold has an opening for exposing the collar, and the shielding shell, the collar, and the shielding layer are all electrically connected via the conductive pad. 
     
     
       10. The cable connector assembly as claimed in  claim 4 , wherein the inner mold defines a notch, and the back cover has a cantilever beam mounted in the notch. 
     
     
       11. A cable connector assembly comprising:
 a mating portion having a front opening forwardly communicating with an exterior along a front-to-back direction, and including a plurality of terminals arranged in two rows opposite to each other in a vertical direction perpendicular to the front-to-back direction with front contacting sections exposed in the opening and rear tails along the front-to-back direction; 
 a flat cable located behind the mating portion and having a plurality of wires to respectively electrically connect to the tails of the corresponding terminals; 
 an inner mold applied upon a rear part of the mating portion and a front part of the flat cable; and 
 a shielding shell enclosing both the mating portion and the inner mold; wherein 
 the shielding shell defines, in the vertical direction, a maximum vertical dimension which is close to that defined by said mating portion; and 
 said shielding shell has, along the front-to-back direction, constant dimensions in both the vertical direction and a transverse direction perpendicular to both said front-to-back direction and the vertical direction. 
 
     
     
       12. The cable connector assembly as claimed in  claim 11 , wherein said shielding shell is metallic. 
     
     
       13. The cable connector assembly as claimed in  claim 12 , wherein some of said wires have corresponding shielding layers exposed to electrically connect to the shielding shell. 
     
     
       14. The cable connector assembly as claimed in  claim 13 , further including means for electrically connecting the shielding layers to the shielding shell. 
     
     
       15. The cable connector assembly as claimed in  claim 11 , further including a back cover located behind the inner mold and within the shielding shell, through which the flat cable extends rearwardly. 
     
     
       16. A cable connector assembly comprising:
 a mating portion having a front opening forwardly communicating with an exterior along a front-to-back direction, and including a plurality of terminals arranged in two rows opposite to each other in a vertical direction perpendicular to the front-to-back direction with front contacting sections exposed in the opening and rear tails along the front-to-back direction; 
 a flat cable located behind the mating portion and having a plurality of wires to respectively electrically connect to the tails of the corresponding terminals; 
 an inner mold applied upon a rear part of the mating portion and a front part of the flat cable; and 
 a shielding shell enclosing both the mating portion and the inner mold; wherein 
 the shielding shell defines, in the vertical direction, a maximum vertical dimension which is close to that defined by said mating portion; 
 said shielding shell is metallic; and 
 some of said wires have corresponding shielding layers exposed to electrically connect to the shielding shell.
